Mr Warninger told ABC news he remembered seeing the same cake in his parents' freezer in their home in the 1950s.

"My grandparents didn't have a good freezer and my folks bought one of those upright freezers and I remember it being packed in tin foil and being told, "You're not allowed to touch that" but that was it. There was never any plans for it, nobody ever talked about it," he told ABC.

"Just the fact that this cake made it through like this is incredible. It’s in perfect shape. It’s been in and out of freezers and been handled a lot. It’s lived through a couple world wars.

"It is just the top of a wedding cake, but how many people have those all these years later? It’s just like a time capsule. I hope to pass it along to one of my kids and maybe they’ll keep it for another 100 years", Warninger said.
